A novel artificial intelligence approach for regolith geochemical grade prediction using multivariate adaptive regression splines

open access: yesGeosystems and Geoenvironment, 2022
The necessity for applying a potent analytical regolith geochemical grade estimator is driven by the reality of mineral exploration. This is because many exploration geologists rely upon the classical geostatistical method of Kriging which oftentimes do ...

Life on Mars, can we detect it?

open access: yesNature Communications, 2023
Searching for evidence of life on Mars is a major impetus for exploration. A new study published in Nature Communications finds that current Mars mission instruments lack the essential sensitivity to identify life traces in Chilean desert samples that ...

A Spectral Comparison of Jarosites Using Techniques Relevant to the Robotic Exploration of Biosignatures on Mars

open access: yesLife, 2018
The acidic sulfate-rich waters of the Meridiani Planum region were potentially a habitable environment for iron-oxidizing bacteria on ancient Mars. If life existed in this ancient martian environment, jarosite minerals precipitating in these waters may ...

Mars Exploration Using Sailplanes

open access: yesAerospace, 2022
We present the preliminary design of sailplanes, used for Mars exploration. The sailplanes mitigate the weight and energy storage limitations traditionally associated with powered flight by instead exploiting atmospheric wind gradients for dynamic soaring, and slope/thermal updrafts for static soaring.
